Top Tier gases must meet some stringent detergency standards, and it's probably a good idea to run them whenever possible. I'm certain that in an emergency, a non-Top Tier gas would be ok, but on a routine basis, a good brand of gas will keep the engine a lot cleaner. Over the long haul, this is probably more important than 93 versus 91 octane.
That’s great information. Thank-you.

It's also the same reason that California ended up with amazing Mexican food, but bafflingly can't provide decent Pizza. There is no good pizza in California, period. You may convince yourself that you found a place that's pretty good, until you sample the proper stuff from elsewhere in the country.

I'll try and tie these three things together by saying the best pizza in CA is from Costco.

Wow I can’t believe you have fuels with low octane or quality levels in the US. Where I live in luxembourg, the lowest is 95 octane, then there’s 98 octane and also 102 octane.

Apples and oranges, or rather MON vs RON. Europe uses the RON and USA uses the average of the RON and MON. European 97 octane is about 91 in the USA.

I didn’t even know this 😌 thanks, the benefits of a forum, we get to learn new things.
I thought the US was stuck in the dark ages with poor fuel quality 😂 when in fact it’s basically the same.
FYI in Europe I think it’s only Germany and luxembourg that have 102 octane. Most other countries max is 98.

Where I live you can also get US 100 octane, (Race Gas), which is probably not available in most places...

thanks for the great discussion!

bottom line, I want to drive in Germany, eat pizza in New York or Chicago, and vacation (only) in California.

sadly I’m in MN...

Please correct me if I am wrong, but the car senses the gas octane rating and adjusts accordingly - the mission is to prevent knocking (pre-ignition in the cylinder) under high stress loads. So max horsepower may be reduced slightly from 93 to 91 octane, but absolutely no other drawbacks. In other words, don't worry about it. Personally, I would be more worried about freshness of the gas / purity.

Correct. Use top tier suppliers and fuel quality shouldn't be an issue.

How does Ethanol affect this discussion? We have 91 no ethanol at Shell and a few others and 94 with ethanol at Petro-Canada.

Generally no but there’s a place in Heber City started by a couple of Deer Valley chefs that’s worthy. Other than that....it’s Costco.

Ethanol is harmful for older engines and fuel lines because the materials of construction weren't designed for it. Fortunately that's been corrected. The other issue is fuel economy as ethanol has about 70% of the energy content per gallon relative to gasoline. Hence, if you purchase gasoline containing 10% ethanol, your mileage will be reduced about 3% (hopefully the price will be too).
